Description

Hello all,

I'm posting here an error I get from Terraform while trying to cascade providers to modules.

I'm using several providers to build my state :

• AWS
• GitLab
• Others

I'm provisioning multiple environments in the cloud so the architecture of terraform is built on module with tree configuration. On a module that is grand child (level -3) I'm deploying gitlab resources:

• Creating a branch
• Uploading a file in the branch This module doesn't work because the provider used is "hashicorp/gitlab" where it should be "gitlabhq/gitlab". In order to solve that I tried to cascade providers in module using meta argument: providers = { aws = aws gitlab = gitlab zipper = zipper } When doing that I get following error: │ The local name "gitlab" in the root module represents provider "gitlabhq/gitlab", but "gitlab" in module.dev-dev represents "hashicorp/gitlab".

This error is only on gitlab provider, AWS provider works fine.

Any help or explanation would be much appreciated.

Thanks' a lot

but "gitlab" in module.dev-dev represents "hashicorp/gitlab".

How did you declare the gitlab provider in the module.dev-dev ? From the error message it seems you either didn't (defaulted to hashicorp/<x>) or you manually specified hashicorp. However, the provider is in the gitlabhq org.

Something like the following in the module will probably help:

terraform {
  required_providers {
    gitlab = {
      source = "gitlabhq/gitlab"
      version = "3.18.0"
    }
  }
}

aws and others may work because they are actually published in the hashicorp org.

Thanks' for your feedback and help. "others may work because they are actually published in the hashicorp org." --> this is what I understood but I don't know how to provide explicit provider. Here is the config: required_providers {

  gitlab = {
    source = "gitlabhq/gitlab"
    version = "3.16.1"
  }
  aws = {
    source  = "hashicorp/aws"
    version = "~> 4.21"
  }

@BastienFerrier Is that how it is defined in the sub module to which you want to pass gitlab to?

[BastienFerrier]

I'm passing it this way:

module dev-dev {
  source = "./Modules/Env_Deployment"
    providers = {
      aws = aws
      gitlab = gitlab
      }
